When an offensive coach such as Jim Harbaugh comes in, it is no surprise that the focus on Stanford is going to be on the offense. However, with the coaching change, there are also going to be some changes on defense.

For starters, the formation has been changed to an "attack" 4-3 defense. What this means is that there will be two defensive ends, a tackle, and a nose tackle. Positions can be changed around but for the most part the defense will follow that specific core.

On the left side of the defensive line, Pannel Egboh and Levirt Griffin will be competing for the majority of playing time. Griffin, a sophomore, had a solid freshman season, but Egboh led the team in tackles for loss and was one of the more consistent defensive players Stanford had.

On the right side of the defensive line is Udeme Udofia, Emmanuel Awofadeju, and Erik Lorig. Udofia likely has the advantage, but it will be interesting to see how he handles the transition from an outside linebacker to a defensive end.

Either way, Udofia is going to see the field, though it remains to be seen if he can win the defensive end position. The player to watch here is Lorig, who was considered to be one of the better tight ends in the country coming out of high school.
